Software Comparison Wiki

I want to find a software comparison website that actually shows features and pricing in a simple format. I’ve used Capterra and such, but they’re too superficial. Does such a site already exist?

If not, how hard is it to build? I can do basic full stack web dev but I’m terrible at aesthetic design. I know MediaWiki is open source, but I get lost in the details and would need a big picture partner to help build it. Any takers?

My impetus is that product pages are full of marketing hype and I hate to spend time testing something and then find out it doesn’t do X when there are people who already knew that and could have contributed that knowledge to a wiki.
